Description
Technical field:
The present invention relates to the illuminating product technical field, refer in particular to a kind of LED street lamp.
Background technology:
The energy is the growing tension of electric power energy especially, for realizing the purpose of environmental protection and energy saving, by LED following advantage is arranged again:
1, the luminous of LED is one-way, do not have diffusion of light, guarantees light efficiency;
2, the source efficiency of LED has reached 90-110lm/W at present, and also has very big development space, and theoretical value reaches 250lm/W.
3, the light colour rendering of LED lamp is more much higher than traditional illuminating lamp;
4, the light decay of LED lamp is little, and the light decay in 1 year uses still to reach road use illumination requirement in 10 years less than 3%;
5, LED is a low-voltage device, and the voltage that drives single LEDs is safe voltage, and series of products list LEDs power mostly is 1 watt, uses the safer power supply of high voltage source so it is a ratio, (for example: street lighting etc.) is specially adapted to the public place;
6, each unit LEDs small pieces has only very small size, thus can be prepared into the device of different shape, and be suitable for variable environment.
9, the life-span is long: can use more than 50,000 hours.
So various LED street lamps more and more are applied among the human lives.The light that sends of light source in the LED street lamp of Chu Xianing sees through diffuser and launches in the market, and for people's trip provides illumination, but still there is deficiency in this LED street lamp: 1, the gripper shoe in the LED street lamp is not made of one piece, and inconvenience is produced in a large number; 2, do not adopt the better seal structure, cause that rainwater enters in the circuit box or enters on circuit board, the led chip under the environment that rains, thereby make it can't operate as normal.3, the reflection shield in the LED street lamp is the round speaker mouth with parabolic surface, and what the reflection shield that also has adopted is the horn mouth of a rectangle or class rectangle, and its reflecting surface also adopts curved surface usually.Such reflection shield mainly is that light is reflexed on the focus, forms concentrated luminous; There is certain deficiency in these reflection shields, because overhead distance is than higher for the light fixture of street lamp, light source luminescent can directly impinge upon just considerably less of bottom surface itself.If still adopt above-mentioned illumination mode with light-ray condensing, will make light shadow surface on the bottom surface, its main lighted region concentrates in less " focus " scope, and other regional brightness obvious zone of " focus " in the center secretly just.Caused the inhomogeneous of reflection ray distribution like this, the effective area of street lamp irradiation is too small, so that there is the blind area between the street lamp.
